								Displays a graph of temperature changes in specified period of time. To add a sensor to the graph use drag and drop
								technique. Sensors are added automatically when the drop occurs. It is possible to add multiple
								sensors to one graph. To modify the graph use the tools form the toolbar of the graph window:
								
								<ul>
									<li><img src="./../../graphics/magnifier--plus.png" />&nbsp;
										<b>Magnify</b> 
										Turns on a magnifier mode. Using the left mouse button select a rectangle of an area to magnify. To leave this 
										mode pres the right mouse button.
									<li><img src="./../../graphics/magnifier--minus.png" />&nbsp;

										Expands a visible area for 150% of current view.
									<li><img src="./../../graphics/magnifier-zoom-fit.png" />&nbsp;
										<b>Adjust</b> 
										Adjusts a visible area of the graph to minimum and maximum visible temperatures.
									<li><img src="./../../graphics/cross-script.png" />&nbsp;
										<b>Delete a sensor</b> 
										Removes a sensor from the graph.
									<li><img src="./../../graphics/guide.png" />&nbsp;
										<b>Cursors</b> 
										Turns on cursors mode. After point of a data point two cursors will appear. It will be possible to read a
										creation time of the sample and its value. Additionally the creation time and value will appear on the status 
										bar of the graph window. To leave this mode press the right mouse button.
									<li><img src="./../../graphics/null.png" />&nbsp;
										<b>3min - 3mth</b>
